Dad's been doing well. His coherency has been improving, and his demeanor has remained fairly upbeat. The nurses say he's a sweetheart, and that he doesn't demand much of anything. Mom says all he ever does is ask for this, that, and then some. ^-^
The only thing that does bother Dad (aside from being in the hospital, of course) is when he's left on his own too long. He gets nervous when he doesn't see anyone around him, but his nurse makes sure to peek her head in fairly often so that he remains calm. And Mom's there as often as she can, which really makes Dad feel better.
That's pretty much all that's been going on lately.
